Getting Facebook session on Wordpress

did you make a test with just the offical FacebookRedirectLoginHelper from official GitHub?I have used the Facebook SDK a couple of times and never had a problem with missing returns.

So I fixed my issue with help from corvuszero's comment.

Here's the code in my ns-facebook.php file:

use Facebook\FacebookSession;use Facebook\FacebookRequest;use Facebook\FacebookRedirectLoginHelper;class WP_Facebook{    var $helper;    var $session;    var $permissions;    var $loginurl;    public function __construct()    {        // Initialize the SDK        FacebookSession::setDefaultApplication('303664476506500', '0197b7f08cc46f051ddb92dfba077484');        $this->permissions = ['public_profile', 'email'];        $this->helper = new FacebookRedirectLoginHelper( home_url('facebook-callback') );        try {            $this->session = $this->helper->getSessionFromRedirect();        } catch (FacebookRequestException $e) {            // handler        } catch (Exception $e) {            // handler        }        if(isset($_SESSION['fb_token'])) {            $this->session = new FacebookSession( $_SESSION['fb_token'] );        }        if($this->session) {            $_SESSION['fb_token'] = $this->session->getToken();        } else {            $this->loginurl = $this->helper->getLoginUrl($this->permissions);        }    }    /**     * Returns the login URL.     *     * @return string     */    public function login_url()    {        return $this->loginurl;    }    /**     * Returns the current user's info as an array.     */    public function get_user()    {        if($this->session) {            /**             * Retrieve User’s Profile Information             */            // Graph API to request user data            $request = new FacebookRequest($this->session, 'GET', '/me');            $response = $request->execute();            // Get response as an array            $user = $response->getGraphObject()->asArray();            return $user;        }        return false;    }    public function get_session() {        return $this->session;    }}
